Bicycle MechanicsBroken bottom bracket? Tacoed wheel? If you're having problems with your bicycle, or just need help fixing a flat, drop in here for the latest on bicycle mechanics & bicycle maintenance.

I just picked up a nice aluminum guerciotti with a 14 speed campy drivetrain and a bunch of other nice parts, but the seat tube lug has a couple fine cracks. These have yet to affect the integrity of the bike, but I would hate for these cracks to open up at 40 mph.....

I guess the question is, can this be repaired? If not, are replacement lugs available?
